Seeed Studio has just unveiled reTerminal HMI terminal that reminds me of the company’s Wio Terminal based on Microchip SAMD51 Arm Cortex-M4F microcontroller with a 2.4-inch display.

But as we’ll look into the details, reTerminal is quite a different beast as a Linux-capable device powered by a Raspberry Pi CM4 module with up to 8GB RAM, equipped with a 5-inch capacitive touchscreen display, and supporting plenty of connectivity options from GIgabit Ethernet to WiFi to LoRaWAN.

  • The Internet of Things: Growth and Challenges

    The small, but growing trend toward deploying containers on embedded devices should improve security, although these are not likely to spread quickly to the smart home. With container solutions, multiple applications with various security levels and even operating systems can coexist in secure, sandboxed containers, which are automatically updated from the cloud with security patches. One related solution is Canonical’s Ubuntu Core, a stripped down, container-like version of Ubuntu that provides automated updates and transaction rollbacks for restoring the software in case of an attack.

  • LOPES helps prioritize your tasks with LEDs | Arduino Blog

    As spotted on Reddit, the Light Based Optical Productivity Enhancement System (LOPES) is an Arduino Nano Every-powered device that lights up depending on the tasks that you have left to complete. The Nano takes input from five copper touch sensor plates on the top, which enable you to add or remove jobs of different priorities.

    Display is via addressable LEDs diffused by a tube, and importance is ranked as either green, yellow or red. As of now, it simply shows how much you have to do without specifics, however, its creator plans to eventually make an app to allow for further interface with a phone.

  • Lenovo M93 Ultra Small Desktop PC- OBS Studio – Week 6

    This is a weekly blog looking at the Lenovo M93 Ultra Small Desktop PC running Linux.

    This week’s blog looks at video recording on the Lenovo M93. When it comes to software, Linux offers a fantastic array of free and open source programs. In the vast majority of areas there’s a wide range of programs to choose from. Sometimes the amount of high quality open source software is bamboozling. But there’s still a few areas which are dominated by a single program. In the case of video recording and streaming, the stand out open source program is OBS Studio.

    Modern graphic cards perform a variety of tasks. They aren’t just designed for gaming. Many cards help offload video encoding and decoding from the CPU. This helps to lower power consumption and free up resources for the rest of the system. In the case of OBS Studio, this program relies heavily on the GPU. But the Lenovo M93 doesn’t have a dedicated graphics card. This ultra small PC uses the Intel HD Graphics 4600, a mobile integrated graphics solution by Intel launched in May 2013. Performance of the graphics unit is widely reported as in the low-end segment.

  • How Google is continuing to chip away at Microsoft's productivity dominance [Ed: Even the Microsoft boosters admit Microsoft is in trouble...]

    The paths of the digital advertising giants may just be beginning to diverge. While Google will remain dependent on advertising revenue for years to come, the company's levelheaded approach regarding threats to that business may be indicative of a broader shift that could have the future of the company looking a lot more like Microsoft than Facebook.

    As we were recently reminded when Microsoft executive Brad Smith testified regarding Google's dominance, the two companies have a long-running rivalry. It has included Microsoft chasing Google in online search and mobile phone operating systems and Google chasing Microsoft in cloud computing, productivity suites, and PC operating systems. The startup display of the Surface Duo, which shows the Microsoft logo on one screen and the Android logo on the other, is a great metaphor for the companies' relationship -- separated by a divide designed to bend but not break.

  • T95 Plus Android 11 TV Box features Rockchip RK3566 AIoT processor, 8GB RAM

    Last month, we wrote about the first Rockchip RK3566 TV box we had seen so far with a new version of the H96 Max TV box running Android 11 with up to 8GB RAM.

    While Rockchip RK3566 processor has multimedia capabilities with 4K HDR video playback and output, it has many other interfaces such as native PCIe and SATA that would not make it as cost-effective as TV Box SoC’s like Rockchip RK3328 or Amlogic S905X4. But this does not stop companies from making TV boxes with the AIoT processor, and T95 Plus TV box offers another option, again with up to 8GB RAM.

  • Arduino Core mbed 2.0 supports Raspberry Pi Pico & Arduino Nano RP2040 Connect - CNX Software - Embedded Systems News

    Last week, we noted and tried the unofficial Raspberry Pi Pico Arduino Core that works on RP2040 boards, including Raspberry Pi Pico. Everything was super early to set up and the blink sample worked just fine.

    But Arduino recently tweeted about the Arduino Core mbed 2.0 release that adds for Raspberry Pi RP2040 boards including Arduino Nano RP2040 Connect and Raspberry Pi Pico boards.

    Arduino first used mbed for their Arduino Nano 33 BLE board as they didn’t have an official Arduino core for the Nordic nRF52840 Cortex-M4 microcontroller, and it appears they’ve done the same for Raspberry Pi RP2040 whose mbed implementation itself relies on the C SDK.

Kernel Leftovers

  • [Intel-gfx] [RFC 00/28] Old platform/gen kconfig options series
  • Patches Resubmitted For Linux With Selectable Intel Graphics Platform Support

    Back in early 2018 were patches proposed for selectable platform support when building Intel's kernel graphics driver so users/distributions if desired could disable extremely old hardware support and/or cater kernel builds for specific Intel graphics generations. Three years later those patches have been re-proposed. The patches then and now are about allowing selectable Intel graphics "Gen" support at kernel configure/build time so that say the i8xx support could be removed or other specific generations of Intel graphics handled by the i915 kernel driver. This disabling could be done if phasing out older hardware support, seeking smaller kernel images, or other similar purposes. The patches don't change any default support levels but leaves things as-is and simply provides the knobs for disabling select generations of hardware.
